Ice maker for IKEA shaped glasses

I thought of creating ice in the shape of my IKEA glasses so that it would exactly fill the glass and I could have a lot of ice.I was inspired by the models that are here and make various balls of ice, etc. I must point out that the inside of the model should be filled with a special varnish for contact with food, otherwise the ice may contain microplastics and chemicals. Use at your own risk. This is a test model. The model consists of three parts that fit together. Water is poured into the large part and when the inner part is pressed, the excess water flows out. Then the part is held in place with TPU rubber so that it does not float out. It is left in the freezer for 3-4 hours. Then the outer part and the inner part are poured with hot water to let the container dissolve. Then carefully turn the inner container and then tap the inner ice with your hand.The ice fits into 380 ml IKEA glasses.
